RJ Graddy (Class of 2011) severed an artery in his leg in the incident, which happened in Austin, Texas -- where he is currently living, according to a GoFundMe page.
The page had raised more than $11,600 for Graddy as of Tuesday afternoon.
In 2010, Graddy broke school records with a 43-foot, 1-inch triple jump at a Teaneck meet.
Graddy's family traveled more than 1,700 to be with him in Texas during rehab and medical procedures.
Proceeds from the GoFundMe will go toward medical bills and flights.
